Honeywell provider

  • Publisher: Honeywell
  • Provider ID: honeywell

Targets

The following targets are available from this provider:

API Validator

Tool to verify proper syntax and compilation completion. Full stack is exercised with the exception of the actual quantum operations. Assuming no bugs, all zeros are returned in the proper data structure.

  • Job type: Simulation
  • Data Format: honeywell.openqasm.v1
  • Target ID: honeywell.hqs-lt-1.0-apival
  • Target Execution Profile: Basic Measurement Feedback

Billing information: No charge for usage.

Honeywell System Model H0

Honeywell Quantum Solutions' Quantum Computer, System Model H0

  • Job type: Quantum Program
  • Data Format: honeywell.openqasm.v1
  • Target ID: honeywell.hqs-lt-1.0
  • Target Execution Profile: Basic Measurement Feedback

Billing information:

  • Priced by Honeywell Quantum Credits (see below).
  • Fee per hour for reserved (exclusive use) time.
Parameter Name Type Required Description
count int No Number of experimental shots. Defaults to 1.
options list No Compiler options. Only one option currently supported: no-opt to disable all optimization

The following equation defines how circuits are translated into Honeywell Quantum Credits (HQCs):

$$ HQC = 5 + C(N_{1q} + 10 N_{2q} + 5 N_m)/5000 $$

where:

  • $N_{1q}$ is the number of one-qubit operations in a circuit.
  • $N_{2q}$ is the number of native two-qubit operations in a circuit. Native gate is equivalent to CNOT up to several one-qubit gates.
  • $N_{m}$ is the number of state preparation and measurement (SPAM) operations in a circuit including initial implicit state preparation and any intermediate and final measurements and state resets.
  • $C$ is the shot count.

Technical Specifications

  • Trapped-ion based quantum computer with laser based gates
  • QCCD architecture with linear trap and two parallel operation zones
  • 6 physical qubits, fully connected
  • Typical limiting fidelity >99.2% (two-qubit fidelity)
  • Coherence Time (T2) ~2 sec
  • Ability to perform mid-circuit measurement and qubit reuse
  • High-resolution rotations (> $\pi$/500)
  • Native Gate set:
    • single-qubit rotations
    • two-qubit ZZ-gates
